'Workaholics' Blake Anderson's Divorce Final

Blake Anderson finalized his divorce about as quickly as the law will allow … TMZ has learned.

The “Workaholics” star’s now ex-wife Rachael Finley filed for the big D back in late May — and 6 months later they’ve reached an agreement and the judge has even given ’em a stamp of approval … according to court docs.

The couple got married in 2012, and have a 3-year-old daughter.

Under California law there’s a cooling off period — meaning even the smoothest of divorces have to wait 6 months — which Blake and Rachael did.
